Frequently Asked Questions
Q1: How does the “Washable” feature help in reducing my operational costs?
Unlike standard disposable filters, our Nonwoven Pocket Filter uses specialized new composite nonwoven fabric that can be cleaned and recycled for application. This extends the product’s lifespan and drastically lowers the frequency and cost of purchasing new replacements.
Q2: Can this filter handle high-velocity air in large commercial buildings?
Yes. It is specifically engineered to handle high air flow with a rated air flow of up to 2700m³/h. The rigid Aluminum alloy or galvanized steel frame ensures that the pockets stay secure and stable even in high-velocity AHU units.
Q3: Will using this filter improve the energy efficiency of my HVAC system?
Absolutely. The optimized pocket design and high-quality synthetic nonwoven media ensure a low initial resistance. This reduces the pressure drop across the filter, allowing your fan motors to operate with a lower load and decreasing overall energy consumption.
Q4: Is the filter frame resistant to harsh industrial environments?
Yes. We offer both Aluminum alloy and galvanized steel frames to provide maximum structural integrity. These materials are selected for their ability to withstand the mechanical impacts and conditions typical in metallurgy, oil, and chemical industry air intake systems.
Q5: How do I ensure there is no air bypass during installation?
Each filter is equipped with a high-quality EVA gasket strip. This ensures a 100% leak-proof fit when installed in your ventilation system, preventing unfiltered air from bypassing the secondary filtration stage.
